Boris FX 8 & 9 closes down Edius 3.3 pro when

I have been working with Edius 3.3 pro for two years now and have never had any problems with it. I just bought Boris FX 8 and have the upgrade 9 with the Edius plug in and ever time I open up Boris while in Edius it closes down both programs. How do I stop this from happening? Thanks

P.S I also ran all the test that Boris have my system
supports all Hardware and all tests were sucessful
